Planar passivated Silicon Controlled Rectifier (SCR) in a SOT186A (TO-220F) "full pack" plastic package intended for use in applications requiring high bidirectional blocking voltage capability and high thermal cycling performance. These devices are intended to be interfaced directly to microcontrollers, logic integrated circuits and other low power gate trigger circuits.

Features and Benefits
  • Direct interfacing with low power drivers and microcontrollers
  • High bidirectional blocking voltage capability
  • High thermal cycling performance
  • Isolated mounting base package
  • Planar passivated for voltage ruggedness and reliability
  • Sensitive gate for easy gate triggering
  • Capacitive Discharge Ignition (CDI)
  • Crowbar protection
  • Inrush protection
  • Motor control
  • Voltage regulation
